Executive Summary Background On 9 June 2005, the Government announced it would invest $8 billion over the next 15 years to develop the Metropolitan Rail Expansion Program (MREP) consisting of three projects: North West Rail Link A new line to Rouse Hill from Cheltenham via Castle Hill with long term plans to extend to Vineyard and the Richmond Line; CBD Rail Link A new tunnel between Central and the North Shore Line at St Leonards including new stations in the CBD and in the lower North Shore, and extra tracks between St Leonards and Chatswood; and South West Rail Link A new line to Leppington from Glenfield Station with long terms plans for a western extension to either Bringelly or Oran Park. The Government also announced that planning for the section of the NWRL from Cheltenham to Rouse Hill would begin immediately, with the line operational by 2017. The North West sector of Sydney is one of the major growth areas in the Sydney Metropolitan region. To improve access to employment and educational opportunities for existing and future residents, and to alleviate the growing traffic congestion in this area, the NSW Government proposes to build the North West Rail Link (NWRL), a new heavy rail line linking Epping with the regional centres of Castle Hill and Rouse Hill. The concept is based on a reference case developed by RailCorp (referred to as the 2017 Reference Scheme), which involves an extension of the current RailCorp operations. The NWRL would provide fast connections to the Lower North Shore, the Sydney CBD and the North Ryde / Macquarie area. It would service established residential areas (approximately two thirds of the proposed route traverses developed land) and it would also service future growth areas identified in the Sydney Metropolitan Strategy City of Cities A Plan for Sydney s Future (DoP, December 2005). The Proponent The Transport Infrastructure Development Corporation (TIDC) is a state owned corporation established under the Transport Administration Act 1988 that develops major transport infrastructure projects on behalf of the NSW Government. The Minister for Transport and the voting shareholders of TIDC have granted consent under Section 18(1) of the Transport Administration Act 1988 for TIDC to undertake the development of the NWRL. Hence, TIDC is progressing the technical studies and preparation of the Environmental Assessment (EA) for concept approval of the NWRL under Part 3A of the Environmental Planning and Assessment Act 1979 (EP&A Act). Purpose of This Report This report has been prepared to support TIDC s project application for the NWRL under Part 3A of the EP&A Act, to assist with the issuing of EA requirements by the Director General of the Department of Planning (DoP) under Section 75F of the EP&A Act. The report also supports an Issued FINAL Page I

application to the Minister for Planning under Section 75M(1) requesting authorisation to proceed with a concept plan for the project. Project Objectives The primary objectives of the proposed NWRL are to: Provide a direct transport link to and from North West Sydney and the global economic corridor (ie. Macquarie-Lower North Shore-CBD-Airport); Connect by rail the major centres of Rouse Hill and Castle Hill, Norwest Business Park, Balmoral Road Release Area and North West Growth Centre; Provide rail network congestion relief in the morning peak with transfer of up to 3000 passengers from the Richmond Line and up to 8000 passengers transferring from the Main West Lines; and Facilitate transit orientated development, with increased commercial and residential development at each station. These objectives are consistent with the objectives of the NSW Government s Sydney Metropolitan Strategy City of Cities A Plan for Sydney s Future. One of the objectives of the Metropolitan Strategy is to improve transport between Sydney s centres by extending the rail and bus networks to connect centres. One of the actions identified to achieve this goal is to plan, and as appropriate, construct the North West CBD South West Rail Links. Need for the Project The NWRL is primarily needed to service established urban and commercial areas in Sydney s North West. It would also cater for future growth areas such as the North West Growth Centre, and the Balmoral Road and Rouse Hill Regional Centre Release Areas. The main benefits of the NWRL would include: Improved accessibility to a trunk public transport line and provision of an alternative to private car usage; Improved accessibility to the Global Arc centres (Macquarie / North Ryde, Chatswood, St Leonards, North Sydney, the CBD and airport) to access employment, educational and cultural facilities; Cost and travel time savings; Reduced congestion on existing rail lines, in particular the Main West Line and reduced need for investment to increase capacity on the Richmond and Main West Lines, to accommodate travel from the North West; Reduced congestion on the road network; and Air quality benefits arising from provision of an alternative to private vehicles and consequential vehicle emissions reductions.

2002 Alignment and Development of the 2017 Reference Scheme Over the past five years, a number of detailed, engineering, operational and environmental studies have been undertaken to determine the feasibility of the proposed NWRL. These studies were undertaken under the management of a Project Control Group (PCG), which included representatives from DoP, RailCorp, Roads and Traffic Authority (RTA) and Ministry of Transport. In 2002 the North West Rail Link Overview Report Connecting Communities (Manidis Roberts, 2002) was released and identified a preferred alignment the 2002 alignment. Comprehensive community consultation was undertaken as part of the exhibition of the Overview Report. In response to issues raised by the Overview Report further studies were undertaken in consultation with key stakeholders including local councils (Hornsby Shire Council, Blacktown City Council and Baulkham Hills Shire Council) and major landholders (e.g QIC, Mulpha Norwest and Bovis Lend Lease). The outcome of these studies and the input from key stakeholders form the basis of the 2017 Reference Scheme. Project Scope 2017 Reference Scheme The scope of the proposal described below is based on the 2017 Reference Scheme. The proposed NWRL would be the principal trunk public transport line in Sydney s North West. It would connect with the Main North Line between Beecroft and Cheltenham Stations and terminate at Rouse Hill Town Centre. The rail link would be twin track, approximately 23km in length and it would include: A 3 km surface quadruplication of the Main North Line between Epping and Beecroft, including station upgrades such as an easy access upgrade at Cheltenham Station and new rail bridge over the M2; A 16 km section in tunnel from the Main North Line to north of Norwest Business Park; A 4 km surface section from north of Norwest Business Park to Rouse Hill; Six new stations (Franklin Road, Castle Hill, Hills Centre, Norwest, Burns Road and Rouse Hill); A train stabling facility at Rouse Hill, which would include facilities for cleaning and maintenance of stabled trains; and Ancillary tunnel support facilities such as tunnel ventilation, tunnel service facility, transformers, power supply, substations, section huts, signalling and a water treatment plant. Construction A number of construction sites would be established. The main work site is likely to be in the Balmoral Road Release Area. Smaller sites would also be required at the stations and in close proximity to the tunnelling operations. Issued FINAL Page III

Operation Upon opening, train services are anticipated to operate every 5-10 minutes in peak periods and every 15 minutes during off-peak periods. These services would travel to Chatswood and the City via the Epping to Chatswood Rail Line (ECRL) or via the Main North Line through Strathfield. The mix of routes would depend on the progress of the CBD Rail Link. Potential Modifications to the 2017 Reference Scheme Potential modifications to the 2017 Reference Scheme that will be subject to further investigations and included within the assessment of environmental issues include: Adjustments to the vertical alignment at Rouse Hill, as proposed by the Town Centre Developer (Bovis Lend Lease); and An alternative horizontal and vertical alignment option to the west of the proposed Castle Hill Station. Preliminary Environmental Assessment The key environmental issues for the proposed NWRL include: Noise and vibration; Indigenous and non-indigenous heritage; Flora and fauna; Traffic, transport, parking and access; Groundwater / geotechnical; Visual impacts and urban design; Flooding; Construction management (including spoil handling); and Social impacts / community involvement. In general, the scope of the previous environment studies, completed as part of the Assessment of Environmental Issues Report (SKM, 2003), is of sufficient standard to inform the EA. This information has been updated for the 2017 Reference Scheme. However, further detailed studies would need to be undertaken as part of the EA. The key issues are described in detail in Section 5 and a proposed scope of work for the EA is provided in Section 6. Issued FINAL Page IV

1 INTRODUCTION 1.1 Background On 9 June 2005, the NSW Government announced that it would invest $8 billion over the next 15 years to develop the Metropolitan Rail Expansion Program (MREP) consisting of three projects (refer to Figure 1-1): North West Rail Link A new line to Rouse Hill from Cheltenham via Castle Hill with long term plans to extend to Vineyard and the Richmond Line; CBD Rail Link A new tunnel between Central and the North Shore Line at St Leonards including new stations in the CBD and in the lower North Shore, and extra tracks between St Leonards and Chatswood; and South West Rail Link A new line to Leppington from Glenfield Station with long terms plans for a western extension to either Bringelly or Oran Park. The Government also announced that planning for the section of the NWRL from Cheltenham to Rouse Hill would begin immediately, with the line operational by 2017. The North West sector of Sydney is one of the major growth areas in the Sydney Metropolitan region. To improve access to employment and educational opportunities for existing and future residents, and to alleviate the growing traffic congestion in this area, the NSW Government proposes to build the North West Rail Link (NWRL), a new heavy rail line linking Epping with the regional centres of Castle Hill and Rouse Hill.

Figure 1-1: Metropolitan Rail Expansion Program 1.3 Purpose of This Report This report has been prepared to support TIDC s project application for the NWRL, to assist with the issuing of EA requirements by the Director General of the Department of Planning (DoP) under Section 75F of the EP&A Act. The report identifies key issues associated with the project and also supports an application to the Minister for Planning under Section 75M(1) requesting the authorisation to proceed with a concept plan for the project. This report has been prepared by Sinclair Knight Merz (SKM) with the assistance of background information supplied by RailCorp and the DoP. 1.4 Project Objectives The primary objectives of the proposed NWRL are to: Provide a direct transport link to and from North West Sydney and the global economic corridor (ie. Macquarie-Lower North Shore-CBD-Airport); Connect by rail the major centres of Rouse Hill and Castle Hill, Norwest Business Park, Balmoral Road Release Area and North West Growth Centre; Provide rail network congestion relief in the morning peak with transfer of up to 3000 passengers from the Richmond Line and up to 8000 passengers transferring from the Main West Lines; and Facilitate transit orientated development, with increased commercial and residential development at each station.

These objectives are consistent with the objectives of the NSW Government s Sydney Metropolitan Strategy City of Cities A Plan for Sydney s Future. One of the objectives of the Metropolitan Strategy is to improve transport between Sydney s centres by extending the rail and bus networks to connect centres. One of the actions identified to achieve this goal is to plan, and as appropriate, construct the North West CBD South West Rail Links. 1.5 Previous Studies 1.5.1 Origins of the Proposal The State Government s commitment to the NWRL was first documented in Action for Transport 2010, released in 1998. On the basis of this plan, the former Transport NSW, in conjunction with the former Rail Infrastructure Corporation and State Rail Authority conducted a Pre-Feasibility Assessment (Maunsell, 2000) to assess a number of travel modes such as bus transitways, light rail and heavy rail. Their suitability for the corridor, capacity, journey times, service quality, connectivity and patronage were assessed and the following conclusions were drawn: The NWRL would be feasible from a technical and engineering point of view; It would be likely to have sufficient levels of patronage to warrant construction of a heavy rail link; It should be constructed as one integrated project (i.e. between Epping and Rouse Hill); and There would be limited time to reserve a surface based heavy rail corridor, given the rate and extent of urban development occurring between Castle Hill and Rouse Hill. The outcomes of the Pre-Feasibility Assessment informed the public release of the Overview Report in 2002 (referred to as 2002 alignment) and subsequent community consultation. The outcomes of this consultation led to further analysis and refinement and contributed to the development of the 2017 Reference Scheme. During the course of this work, alternative modes and routes were assessed. On the basis of the conclusions reached in the Pre-Feasibility Assessment (Maunsell, 2000), further investigations were undertaken to evaluate the feasibility and potential of the project. The key studies undertaken to date include: Project Need, Feasibility & Alternatives Land Use and Modal Integration (Maunsell, 2002) Patronage Study (Parsons Brinkerhoff, 2005) Alternatives Study (Booz Allen Hamilton & GHD, 2005) Financial and Economic Construction Methodology and Cost (Tenix, 2005) Economic Appraisal (Douglas Economics, 2005) Operations & Network Stabling - Assessment of SRA Train Stabling Requirements in the North West Sector (GHD, 2002) Western Extension Pre-Feasibility (GHD, 2003) Issued FINAL Page 3

Operational Requirements Study (Halcrow, 2005) Engineering & Technical Concept Engineering Study (Arup, 2002) Balmoral Road Study of Rail Route Options (Arup, 2003) Geotechnical Investigation (Arup, 2003) Station Concept Design (Hassell, 2005) Rail Infrastructure Study (Arup, 2005) Property Land Acquisition Study (Creer & Berkley, 2001) Land Acquisition Programme (Creer & Berkley, 2003) Corridor Preservation Study (HillPDA, 2005) Environmental Assessment of Environmental Issues (Sinclair Knight Merz, 2003) 1.5.2 Patronage Study Parsons Brinkerhoff (2005) undertook a detailed patronage study of a number of alternatives, including the NWRL. The study found that: Rail demand is predicted to double, and be well in excess of capacity, along the Richmond Line and parts of the Main West Line by 2021 if the proposed NWRL does not proceed; In the absence of the NWRL car travel times from the North West area are expected to increase beyond current levels as demand growth exceeds capacity growth; The NWRL would decrease time taken for patrons to access the rail network by up to 30 minutes and the average access distance to a rail station would decrease by about 50% across the study area, from 12km to 6km; The NWRL would substantially reduce future loadings on the Richmond and Main West Lines; The NWRL would draw patronage from the Main North Line between Hornsby and Epping; Loadings on the Epping to Chatswood Rail Line (where there would be spare capacity) would increase by up to 90% in direction of the City and 50% in the opposite direction. These increases would flow into the North Shore Line where an additional 6-7 train loads are predicted across the Harbour Bridge in the two hour morning peak; Almost 80% of the system usage of the NWRL in the morning peak would comprise trips that originate at one of the proposed new stations and finish at destinations outside the study area (i.e. on other rail lines). Almost 20% of trips would originate outside the study area and finish in the North West. Less than 5% of trips would start and finish in the study area; and The NWRL is forecast to be a heavy use line with around 14,000 passengers in 2021 in the 2hr AM peak (refer to Figure 1-2).

It was previously estimated that the project would have a capital cost of approximately $2.8 billion (in $2005) including land acquisition, new rolling stock required and the need for external works. This estimate is currently under review by TIDC. 1.5.4 Environmental Assessment Report An environmental study, Assessment of Environmental Issues Report (SKM, 2003), was prepared to investigate specific issues such as flora and fauna, water quality, hydrology and hydraulics, groundwater, indigenous and non-indigenous heritage, noise and vibration, and landscape and visual characteristics. Information gathered during these studies was used to produce a series of constraints maps to allow an understanding of key constraints in relation to the 2002 alignment. The report also summarised the key community issues and social constraints identified from submissions on the Overview Report. The environmental and social constraints led to changes to the alignment, resulting in the 2017 Reference Scheme (refer to Section 1.7). 1.6 Alternatives Considered Booz Allen Hamilton & GHD (2005) undertook an alternatives study in which approximately 150 alternatives including various rail alignments and station locations, and different modal options (heavy rail, light rail, transitways), were evaluated. A short list of 20 options was identified and the seven Issued FINAL Page 5

highest ranking options were assessed against a set of criteria. The study found that the NWRL is the preferred option because it: Optimises economic costs and benefits; Provides opportunities for extension and connectivity to the Richmond Line; Has strong direct connectivity to the North West; Facilitates significant transit orientated development along the corridor; Has strong public transport mode share changes; Minimises undesirable environmental and social impacts in already developed areas (the heavy rail options would require less acquisition of existing residential properties than light rail or transitway options); and Heavy rail options would provide greater travel cost and time savings in comparison to light rail and transitway alternatives. 1.6.1 Modifications to the 2002 Alignment Since the Concept Engineering Study (Arup, 2002) and exhibition of the Overview Report in 2002, modifications to the NWRL 2002 alignment have occurred (refer to Figure 1-3). These changes have arisen from the outcomes of the specialist studies and their recommendations and the need to address concerns raised by the community, Baulkham Hills Shire Council and individual developers. The key modifications are: The bored tunnel alignment between the Beecroft dive structure and Franklin Road Station In some locations, the route has been re-aligned by up to 250m; The bored tunnel and surface sections of the alignment between Norwest Business Park and Burns Road Station Approximately 5km of the route has been re-aligned and consequently the western portal has been re-located further west; The stabling facility has been moved about 500m to the east, to be adjacent to Windsor Road; The NWRL project scope has been expanded to include the quadruplication of the Main North Line from Epping to Beecroft. Issued FINAL Page 6

Figure 1-3: The 2017 Reference Scheme and the 2002 Alignment Issued FINAL Page 7

Between the Beecroft dive structure and Franklin Road Station, the alignment was modified to simplify and straighten the alignment. In the Balmoral Road Release Area, between Norwest Business Park and Burns Road Station, the alignment was modified to minimise impacts on: Cumberland Plain Woodland (an endangered ecological community); The northern portion of the future Bella Vista Housing Estate by avoiding the requirement for a large cutting through the development; Sensitive landuses at the Hillsong Church (including an auditorium and a proposed television and radio studio); and Flooding and environmental risks associated with crossing Elizabeth Macarthur Creek in cutting. The train stabling facility was re-located to be above the assumed Probable Maximum Flood (PMF) level for Second Ponds Creek and to minimise impacts on Cumberland Plain Woodland. 1.7 Project Scope The scope of the proposal described below is based on the 2017 Reference Scheme. The proposed NWRL would be the principal trunk public transport line in Sydney s North West. It would connect with the Main North Line between Beecroft and Cheltenham Stations and terminate at Rouse Hill Town Centre. The rail link would be twin track, approximately 23km in length and it would include: A 3 km surface quadruplication of the Main North Line between Epping and Beecroft, including station modifications such as an easy access upgrade at Cheltenham Station and new rail bridge over the M2; A 16 km section in tunnel from the Main North Line to north of the Norwest Business Park; A 4 km surface section from north of Norwest Business Park to Rouse Hill; Six new stations (Franklin Road, Castle Hill, Hills Centre, Norwest, Burns Road and Rouse Hill); A train stabling facility at Rouse Hill, which would include facilities for cleaning and maintenance of stabled trains; and Ancillary tunnel support facilities such as tunnel ventilation, tunnel service facility, transformers, power supply, substations, section huts, signalling and a water treatment plant. 1.7.1 Construction A number of construction sites would be established. The main work site is likely to be in the Balmoral Road Release Area. Smaller sites would also be required at the stations and in close proximity to the tunnelling operations. 1.7.2 Operation Upon opening, train services are anticipated to operate every 5-10 minutes in peak periods and every 15 minutes during off-peak periods. These services would travel to Chatswood and the City via the Epping to Chatswood Rail Link (ECRL) or via the Main North Line through Strathfield. The mix of routes would depend on the progress of the CBD Rail Link. Issued FINAL Page 8

1.7.3 Potential Modifications to the 2017 Reference Scheme Potential modifications to the 2017 Reference Scheme that will be subject to further investigations and included within the assessment of environmental issues include: Adjustments to the vertical alignment at Rouse Hill, as proposed by the Town Centre Developer (Bovis Lend Lease); and An alternative horizontal and vertical alignment option to the west of the proposed Castle Hill Station. 1.8 Current TIDC Studies TIDC is currently undertaking a range of studies including: Engineering design review to define the project scope and identify the requirement for further studies; Property acquisition requirements; Independent review of the patronage forecasts; and Constructability report that includes the construction methodology, project schedule and cost estimate. Arising from the initial work being undertaken by TIDC, the need for further studies has been identified and includes: Cheltenham Station access arrangements, following quadruplication; Park-and-ride requirements / station design; NWRL support facilities requirements study; Utilities study; Scope and design of 3 km quadruplication of the Main North Line from Epping to Beecroft; and Turnback arrangements at Rouse Hill. Details of these studies will be reported on in the EA. 1.9 Consultation 1.9.1 Authority Consultation A Planning Focus Meeting (PFM) for the proposed NWRL was held on 19 th December 2005 at SKM s office in St Leonards. The minutes from the PFM are provided in Appendix A. Representatives from the following organisations attended the PFM: DoP; RailCorp; Department of Environment and Conservation; RTA; Ministry of Transport; Issued FINAL Page 9

Hornsby Shire Council; Blacktown City Council; Hawkesbury City Council; and Integral Energy. Baulkham Hills Shire Council was unable to attend the PFM but has been closely involved in the development of the NWRL proposal through the Balmoral Road Release Area. A separate briefing was provided to Baulkham Hills Shire Council officers in January 2006. At the time of the PFM, no works were proposed within the Parramatta Local Government Area (LGA) and as such, a representative from Parramatta City Council did not attend the PFM. The quadruplication of the line between Beecroft and Epping Stations may result works within the Parramatta LGA. Therefore, should works be proposed within Parramatta LGA, a meeting would be held with Parramatta City Council to brief them about the project. The key issues raised at the PFM were: The traffic impacts associated with construction (i.e. haulage routes) and operation (i.e. parking and access arrangements); Urban design treatments; Potential impacts on heritage items, threatened species and endangered ecological communities; Potential impacts on the community (e.g. noise and vibration); Co-ordination between government agencies and organisations; Consistency of the proposal with new environmental planning instruments; Consequences of not proceeding; Interaction with M2 to F3 road alignments; Impacts on existing utilities infrastructure such as the 132kV Integral Energy transmission line within the Balmoral Rd Release Area; and Consistency with, and cumulative impacts from, the different modes of transport in the North West. 1.9.2 Community Consultation The early planning stages of the project and the 2002 preferred route for the NWRL between Epping and Rouse Hill Town Centre were outlined in the North West Rail Link Overview Report Connecting Communities (Manidis Roberts, 2002). The release of this report in 2002 provided the first opportunity for public comment on the then preferred alignment of the NWRL. The aim of the preliminary consultation was to provide practical information about the proposed rail link and encourage community input into the early planning process. Some of the positive comments received were: The NWRL would be a vital transport link for a growing area of Sydney; It would reduce traffic congestion in Sydney's North West; Issued FINAL Page 10

It would also reduce emissions and smog, improving Sydney's air quality; The new rail line would be used by the majority of respondents; and Property values would rise as a consequence of improved access to public transport. Key environmental concerns raised by the community included: Construction management with respect to noise and vibration, spoil disposal, air quality (dust) and water quality impacts; Impacts on threatened species and endangered ecological communities; Impacts on indigenous and non-indigenous heritage; Visual impacts and landscaping treatments; Flooding impacts; Property impacts; and Impacts on groundwater. Other concerns related to detailed design elements, such as at stations, and traffic management. It is acknowledged that the NWRL has the potential to impact residents and businesses both directly (through property acquisition) and indirectly (through amenity issues such as noise, dust and traffic). Opportunities for community involvement in the development of the proposed NWRL have included an established freecall 1800 phone line, a NWRL website and email address, which have been operational since 2002 under the management of DoP, and now TIDC. Throughout this period consultation has continued with Councils. TIDC is currently developing a consultation strategy to ensure there is effective, ongoing liaison with the community. 1.10 Report Structure The structure of this report is as follows: Section 2 outlines the planning and development process; Section 3 outlines the need for the project; Section 4 describes the scope of the project; Section 5 provides a preliminary assessment of the key issues arising from the project; Section 6 outlines the proposed scope of the EA; Section 7 outlines the TIDC s Draft Statement of Commitments for the project.

2 PLANNING AND DEVELOPMENT PROCESS 2.1 Strategic Planning Context 2.1.1 Sydney Metropolitan Strategy In December 2005, the NSW Government released the Sydney Metropolitan Strategy City of Cities A Plan for Sydney s Future. The Strategy forecasts that by 2013, there will be approximately 15,000 new dwellings in existing areas in Sydney s North West and by 2031, another 55,000 dwellings in existing areas (i.e. a total of 70,000 dwellings). This highlights the forecast growth in established urban areas and the need to provide reliable public transport in these areas. As part of the Strategy, the Government plans to direct new greenfield development to nominated growth centres in North West and South West Sydney. A key component of these new greenfield areas would be to provide access to local jobs, access to safe and reliable public transport, local schools, shops and parks. The North West Growth Centre, located at the northern extent of the NWRL project, will accommodate a further 60,000 new dwellings and over 300 hectares of land for business / employment uses and a further 250 hectares for industrial uses. This is in addition to development that will occur elsewhere in North Western Sydney, such as at Rouse Hill and in the Balmoral Road Release area. The Government s intention to plan, and as appropriate, construct the NWRL is documented in the Transport component of the Strategy. It also identifies Castle Hill as an existing regional centre and Rouse Hill as a future regional centre (i.e. a major shopping and business centre for the surrounding area with a full scale shopping centre, council offices, office and residential buildings, central community facilities and a minimum of 8,000 jobs). Norwest Business Park is identified in the Strategy as a specialised centre (i.e. an area that contains research or business activities that perform vital economic and employment roles across the metropolitan area). The Balmoral Road Release Area, which comprises approximately 400 hectares of predominantly rural zoned land within Baulkham Hills Shire, is planned to be re-zoned for residential, commercial and employment development, and for public services and facilities such as open space and schools. It will house approximately 16,000 people and accommodate approximately 6,150 new dwellings. The Rouse Hill Development Area will be a mixed-use centre, comprising community, residential, retail, commercial, educational and recreational activities. Approximately 150,000m 2 of mixed retail / commercial space and 2,000 dwellings are proposed in the development area. Residential and commercial development in the North West is planned to lead to significant increases in population and employment, with associated increases in travel demand. Development in new release areas will dominate growth. It will be accompanied by in-fill development and, particularly in areas of high land values, re-development of land to new, more intensive uses. Whilst the NWRL is primarily required to service established urban areas in Sydney s North West, it would also service the transport needs of the future growth areas. Issued FINAL Page 12

As discussed above, the Government s intention to plan, and as appropriate, construct the NWRL is documented in the Strategy. The NWRL also supports other elements of the Strategy by: Providing effective public transport to existing development areas in the North West; Providing rail to the two North West regional centres (Rouse Hill and Castle Hill) and a specialised centre at Norwest Business Park; Linking the North West to major centres of employment within the Global Arc ; Supporting North West land releases; Providing a link to services (eg. health and education); and Reducing car dependency and lowering vehicle kilometres travelled. 2.2 NSW Planning Legislation 2.2.1 Part 3A of the EP&A Act Part 3A of the EP&A Act establishes an assessment and approval regime for major infrastructure projects. Part 3A applies to development that is declared to be a Part 3A project by either a State Environmental Planning Policy or Ministerial Order (Section 75B). The NWRL has been declared to be a project to which Part 3A applies by an order made by the Minister on 7 April 2003. The assessment and approval process under Part 3A is summarised in Figure 2-1. Concept Plan Division 3 of Part 3A provides a process for the environmental assessment and approval of concept plans for projects where the Minister has authorised or required a proponent to submit a concept plan under Section 75M of the EP&A Act. This report has been prepared to support a request that the Minister authorises TIDC to submit a concept plan for the NWRL under Section 75M. The NWRL is a large scale, long-term and complex infrastructure project for which conceptual strategic planning work has already been undertaken. The establishment of a rail corridor through a concept plan approval process will ensure better integration of land use and transport planning in the LGAs affected by the project. Submission of a concept plan will also enable further community involvement in the strategic planning phase and in the refinement of the project. In addition, it will provide the proponent with a greater level of certainty while retaining the necessary flexibility for the refinement of design. A concept plan is subject to the environmental assessment process prescribed under Part 3A (Section 75N). Once the Minister has authorised or required the submission of a concept plan, the environmental assessment process involves the following key steps: Issued FINAL Page 13

Ministerial Order requires assessment under Part 3A Planning Focus Meeting We are here Project application & Preliminary Environmental Assessment (PEA) Minister authorises submission of Concept Plan under Part 3A. Concept Plan describes scope, development options, staging and addresses requirements of the Director General Director General provides Environmental Assessment (EA) requirements TIDC prepares and submits Concept Plan, EA & Draft Statement of Commitments (if required) Note: Independent Hearing and Assessment Panel could be triggered at any of these stages Public exhibition of EA for a minimum of 30 days TIDC responds to submissions if required, prepares Preferred Project Report and/or revised Statement of Commitments. If there are significant changes, the Director General may require public availability of the Preferred Project Report Director General provides Assessment Report to Minister for Planning Minister for Planning determines Concept Plan and if approved, sets conditions for further assessment and/or project approvals required Figure 2-1: Part 3A Planning Process for the NWRL Issued FINAL Page 14

The Director-General will prepare the EA requirements for the project in consultation with other relevant authorities (Section 75F). TIDC will be notified of these requirements which may include a requirement for TIDC to give a Statement of Commitments relating to environmental management and mitigation measures; The Minister may constitute an independent hearing and assessment panel to assess any aspect of the project (Section 75G); TIDC would then be required to prepare an EA in accordance with the Director-General s requirements (Section 75H(1)); The EA would be publicly exhibited for at least 30 days. The Director-General would provide copies of submissions and a preferred route report (if required) outlining any changes to the project as a result of the submissions (Section 75H); The Director-General would prepare a report to the Minister on the EA for the purpose of the Minister s determination of whether to grant approval to the concept plan (Section 75I); The Minister would determine whether to approve or refuse the concept plan. This report also contains a Preliminary Environmental Assessment upon which the Director-General may prepare EA requirements for the concept plan. When giving approval for a concept plan, the Minister may make any (or a combination of) the following determinations under Section 75P: Further environmental assessment requirements for approval to carry out the project or a particular stage of the project under Part 3A; That approval to carry out the project or a particular stage of it is subject to Part 4 or Part 5 of the EP&A Act; That no further environmental assessment is required for the project or any particular stage of it (in which case the Minister may approve or disapprove of the carrying out of the project under Part 3A without further application or environmental assessment). 2.2.2 Local Planning Instruments The proposed NWRL would be located within the Hornsby LGA, Blacktown LGA, Baulkham Hills LGA, and possibly Parramatta LGA, and hence is subject to the provisions of the Hornsby Local Environmental Plan (LEP) 1994, Blacktown LEP 1988, Baulkham Hills LEP 2005 and Parramatta LEP 2001. The proposed NWRL passes through various zones in these LGAs and would be permissible with consent in some zones and permissible without consent in others. The Ministerial Order of 7 April 2006 making the NWRL proposal subject to Part 3A makes the Minister for Planning the approval authority and depending on how the Minister exercises his discretion under Section 75P, may override the need for consent under Part 4 or approval under Part 5 of the EP&A Act. Some amendments to planning instruments have been introduced to accommodate the proposed NWRL in the new release areas. Clause 55 of the Baulkham Hills LEP states that consent must not be Issued FINAL Page 15

granted to the carrying out of development on land within the Rouse Hill Regional Centre unless the Council has taken into consideration the future provision of a rail link to and through the Rouse Hill Regional Centre. A Draft LEP for the Balmoral Road Release Area has also been prepared and identifies the proposed rail corridor for re-zoning. The re-zoning accommodates the rail corridor and a new Transit Centre at Burns Road. One of the aims of the Draft LEP is to support those residential neighbourhoods and the future population with a range of urban support uses and services including employment areas, transport, public open spaces, commercial, educational and utility services. The proposed NWRL would provide a reliable and efficient public transport service for Sydney s North West and hence, is consistent with this aim. The Draft LEP also introduces a new clause relating to development within 60m of the rail corridor which states that consent must not be granted to the carrying out of development unless the consent authority is satisfied that the development incorporates appropriate noise attenuation and vibration minimisation measures, and the design and location of the development is such that it will not interfere with the operation of the rail line and associated facilities. 2.2.3 Regional and State Planning Instruments A number of Regional Environmental Plans (REPs) and State Environmental Planning Policies (SEPPs) are relevant to the proposal. These include: SREP 19 Rouse Hill Development Area; SREP 20 Hawkesbury-Nepean Catchment (No. 2 1997); SEPP 11 Traffic Generating Developments; SEPP 19 Bushland in Urban Areas; SEPP 44 Koala Habitat Protection; and Draft SEPP (Sydney Region Growth Centres) 2006. The Draft SEPP (Sydney Region Growth Centres) 2006 was recently exhibited. It sets out the statutory plans and processes that will apply in the growth centres. One of the aims of the Draft SEPP is to coordinate the release of land for urban and employment development in the North West and South West growth centres of the Sydney Region. The Draft SEPP includes revised precinct boundaries and constraints maps showing areas where development is constrained by flooding and/or conservation. The last kilometre of the NWRL to Rouse Hill and the stabling facility are within the boundaries of the Growth Centre. A further amendment to SEPP 63 - Major Transport Projects is also likely to include the NWRL to preserve the identified rail corridor. 2.2.4 State Legislation Table 2-1 identifies the licences and approvals that may be required for the construction and operation of the proposed NWRL.

Relevant Council NB. The operation of the NWRL would be covered through required amendments to the existing Environment Protection Licence held by RailCorp. If approval to carry out the project is granted under Part 3A of the EP&A Act, the following authorisations would not be required: A permit under Section 201, 205 or 219 of the Fisheries Management Act 1994; An approval under Part 4, or an excavation permit under Section 139, of the Heritage Act 1977; A permit under Section 87 or a consent under Section 90 of the National Parks and Wildlife Act 1974; An authorisation referred to in Section 12 of the Native Vegetation Act 2003 (or under any Act to be repealed by that Act) to clear native vegetation; A permit under Part 3A of the Rivers and Foreshores Improvement Act 1948; A water use approval under Section 89, a water management work approval under Section 90 or an activity approval under Section 91 of the Water Management Act 2000. 1 Depending on how the Minister exercises his powers under Section 75P of the EP&A Act, consent under Section 138 of the Roads Act 1993 and an Environment Protection Licence under the Protection of the Environment Operations Act 1997 may not be able to be refused if it is necessary for carrying out an approved project and may be required to be substantially consistent with the approval under this Part, as a result of Section 75V of the EP&A Act. Issued FINAL Page 17

Whilst authorisations would not be required, TIDC would closely consult with the agencies that administer these Acts to ensure the intent of the Acts are observed. 2.3 Commonwealth Legislation Potential impacts of the proposed NWRL that may trigger assessment under the Commonwealth Environment Protection and Biodiversity Conservation Act, 1999 (EPBC Act) are limited to potential impacts on Commonwealth land and ecological impacts. There are four sites adjacent to the alignment of the proposed NWRL that are under the control of the Commonwealth. Three of these sites are located in the vicinity of the tunnel section and one site is located in the vicinity of the surface section of the route. These sites would not be affected by the physical works associated with the proposed NWRL. The flora and fauna assessment completed in 2003 concluded that the proposal is not likely to affect the habitat or prey base of migratory species in the locality. The assessment also concluded that there are unlikely to be significant impacts on nationally threatened species due to the small quantity of habitat likely to be impacted relative to the extent of comparable and better quality habitat throughout the region, and secondly that the site contains only potential foraging habitat and does not cater for breeding life-cycle requirements of these species. Three nationally threatened ecological communities are in the study corridor, namely Cumberland Plain Woodland, Turpentine-Ironbark Forest in the Sydney Basin Bioregion and Blue Gum High Forest of the Sydney Basin Bioregion. The largest and highest quality areas of Cumberland Plain Woodland were identified at the end of the route to the west of the proposed Rouse Hill stabling yards. A number of other, generally lower quality, portions of this community may be removed as part of the proposal. The Turpentine-Ironbark Forest community is poorly represented within the study area and is located in parkland referred to as the Beecroft Village Green on Beecroft Road. The park is regularly mowed and maintained and it is within the tunnel section of the alignment. The community contains only representative trees and there is no natural shrub or groundcover vegetation and it is unlikely that tunnel construction operations beneath the park would impact on the root structure of the trees. An area of Blue Gum High Forest is located adjacent to the proposed Franklin Road construction site but it would not be directly affected by the proposal. This site contains good quality remnant and regrowth vegetation that is considered worthy of conservation. As a precautionary measure, a referral to the Environment Minister under the EPBC Act would likely be made. Issued FINAL Page 18
